OF BRUSSELS, BELGIUM STABILIZER- FOR USE-ON MOTOR VEHICLES Application filed July 30, 1928, Serial No; 296,316, and in Belgium August 10, 1927.

This in vention relates to the suspension of motor vehiclcchassis on their axles and has for its objcct'adevice whereby the chassis tends to-reniain parallel, laterally, to the axles.

The invention will be described with reference to the back axle of a motor vehicle, on which the chassis is suspended by a spring at-each'end of the axle, but it isapplicable to the suspension on any axle by any system of springs.

In the accompanying drawings Figure 1 represents diagrammatically the chassis of a motor vehicle suspended on a back axle; v

Figure 2 is an elevation, partly in section, of a constructional form of the device, with parts removed, and j Figure 3 is a horizontal section taken on the line33 of Figure 2.

The general principle involved in the invention will be best understood from Figure 1 in which theehassis p is shown as suspended by springs 1, 1, on the back axle casing 2. Two levers g, h, are pivoted at b, a, respectively to'the casing 2. Theirinner ends 6, f, are

connected together, either by sliding pivot as shown in Figure 1, or by toothed gearing as illustrated in Figures 2Iand 3. Their outer ends are pivoted at 3 to members 4 attached to the chassis, provision being made for small lateral motion, as for instance, bythe sliding pivots shown at 3. v

If, say, downward pressure be applied to the left-hand side of the chassis, causing this side to descend, pressure in applied through the levers g, 71 tending to ca, e the righthand side of the chassis to descend to a corresponding extent.

. The connection between the outer ends of. the levers g, h, and the chassis maybe through cushioning springs, permitting a small movement of the levers relatlve to the chassis,

either vertically or horizontally (fore and aft of the chassis) or both. I

As in'dicatedin Figures 2 and 3, the two levers g. h, are pivoted within a box or casing a, which is fixed rigidly to the back axle casing by any suitable means. Two cylindrical pivots b, c, rigidly attached tothe so-ealled bottom plate (1 of the casing (1, act as the points of articulation of the ends or feet 6 and f of the levers g and h, respectively. The two ends a, f, are provided each with a toothed sector 71, j, respectively, which are always in mesh and can work either in oil, graphite or other lubricant, or dry.

As shown in Figure 3, the outer end ofeach of the levers g,'h, slidingly engages with a cylindrical plunger acted upon by two symmetrically disposed springs Z, m, within 'a housing or box a, rigidly connected to the chassis.

The casing ais closed by a lid Figure 3, and the members contained in said casing are protected against dust and water, by flexible dust-tight closures or sheaths 9 made of leather or the like,' fixed to respectively opposite ends of the casing a and also to the boxes n.

By referring particularly to Figures 1 and 2, it will readily be seen that any angular movement of either of the levers g, k, consequent upon a vertical displacement of the side frame of the chassis p in relation to the casing a and the axle casing to which said casing is attached, will be transmitted through the agency of the toothed sectors '5 and j, to the other of said levers so that bothof these levers must necessarily move correspondingly, the sliding engagement of the levers g, k,

- Finally, to damp or brake-theangularmovev ments of the levers g, h, the bosses e and f of said levers are gripped between discs or washers a: of wood or other friction resisting material under the action of springs s the pressure exerted by which can be regulated at will by nuts t turnable on the reducedthreaded ends of the pivots b and 0 and easily accessible from outside by removing the cap a bolted to the lid v of'the casinga.

Having described in invention, I declare that what I claim and esire to secure by Let ters Patent is 1. In adevicefor the'chassis of a motor vehicle in relation to a road-wheel axle, the combination with said axle and a casingfltherefor, of two pivots in fixed relation to the casing having parallel axes, two levers respectively turnable on the pivots, intermeshing toothed sectors on the inner ends of the two levers, housings fast to the sides I of the chassis receiving the outer ends ofthe levers, and springs within the housings, adapted to exert pressure in relatively opggsite directions on eachofthe said outer en 2.
